The average benchmark score confirms the overall picture: the Ultra X7 358H averages 40967 across all tests, placing it in the 87th percentile of all CPUs, while the i7-14701E averages 33206, placing it in the 83rd percentile.

Architecture Differences

The two processors come from entirely different design generations and market segments. The Core i7-14701E uses the Raptor Lake architecture on a 10 nm process node, built by Intel. It is a desktop part with 8 cores and 16 threads, using Intel Socket 1700. The Core Ultra X7 358H uses the Panther Lake codename on a 3 nm process node, also built by Intel, but it is a mobile part with 16 cores and 16 threads on Intel BGA 2540.

The absence of hyperthreading on the Ultra X7 358H is notable: it packs 16 physical cores but only 16 threads, while the i7-14701E delivers 16 threads from 8 physical cores. This structural difference explains why the Ultra X7 wins heavily in multi-threaded PassMark tests despite the i7's higher clock speeds.

Cache layouts differ substantially. The i7-14701E provides 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Ultra X7 358H offers 192 KB of L1 per core, 3 MB of L2 per core, but only 18 MB of shared L3. The larger L3 on the desktop part helps it in Cinebench R23 multi-core, while the larger per-core L1 and L2 on the mobile part may contribute to its PassMark strengths.

Memory support diverges completely. The i7-14701E supports DDR4 and DDR5 in dual-channel configuration, and includes ECC memory support. The Ultra X7 358H supports only LPDDR5X in dual-channel, with a recorded memory bandwidth of 153.6 GB/s, and lacks ECC. The i7-14701E offers PCIe Gen 5 with 16 lanes (CPU only), while the Ultra X7 358H offers PCIe Gen 5 with only 4 lanes.

Process technology gives the Ultra X7 a significant manufacturing advantage: 3 nm versus 10 nm. This explains its much lower 25 W TDP against the i7-14701E's 65 W TDP, despite having twice as many physical cores.

Clock speeds favor the desktop part. The i7-14701E has a base clock of 2.60 GHz and a boost of 5.40 GHz. The Ultra X7 358H has a base of 1.90 GHz and a boost of 4.80 GHz. The 0.60 GHz boost advantage for the i7 correlates with its single-core wins.

Integrated graphics differ: the i7-14701E uses UHD Graphics 770, while the Ultra X7 358H uses Arc B390. Both processors are currently marked as Active in production, with release dates of June 30, 2024 for the i7 and January 4, 2026 for the Ultra.

Where Each One Wins

The Core i7-14701E wins specifically in Cinebench R23 multi-core and single-core, plus Cinebench R15 single-core and PassMark single-thread. These results indicate a processor that excels in sustained rendering workloads with high clock speeds and a large shared cache. The 50.6% single-core advantage in Cinebench R23 is particularly striking, suggesting the 5.40 GHz boost clock delivers real performance in lightly threaded tasks.

The Ultra X7 358H wins across the remaining spectrum, including all PassMark computational tests except single-thread. Its 42.9% encryption advantage and 47.8% prime number advantage suggest strong integer and cryptographic throughput, likely from the higher core count. The 40.4% floating point math lead shows the 16 physical cores handle parallel arithmetic workloads efficiently.

For data compression, the Ultra X7 leads by 14.9%, which matters for file archiving and database workloads. For random string sorting, it leads by 27.7%, indicating faster memory access patterns despite the smaller L3 cache.

The i7-14701E's 18.4% Cinebench R23 multi-core win is worth scrutiny. The R23 test scales well with both core count and cache size, and the 33 MB L3 appears to compensate for fewer physical cores. The Ultra X7's 18 MB L3 likely bottlenecks in this specific workload.

The Verdict

The data indicates two processors optimized for opposite ends of the workload spectrum. The Intel Core i7-14701E delivers superior single-core performance in most tests and wins Cinebench R23 multi-core despite having half the physical cores. Its 33 MB L3 cache and 5.40 GHz boost clock make it the stronger choice for rendering workloads that scale with large caches and high clock speeds.

The Intel Core Ultra X7 358H wins the majority of tests, particularly in PassMark computational suites. Its 16 physical cores provide substantial advantages in encryption, floating point math, and prime number calculations. The 3 nm process node allows this performance at 25 W TDP, a fraction of the i7's 65 W TDP.

The average benchmark score gap is substantial: 40967 versus 33206, a difference of roughly 23%. The percentile ranks confirm this, with the Ultra X7 at 87th and the i7 at 83rd. However, the i7's 50.6% single-core win in Cinebench R23 cannot be ignored for applications that depend on lightly threaded performance.

For desktop systems where power consumption is less critical and single-core speed matters most, the i7-14701E delivers. For mobile or power-constrained environments where multi-threaded throughput dominates, the Ultra X7 358H is the clear data-supported choice.
